Content preview: Hi Domenico, Which filter settings did you choose to obtain the CW filter? I also used vlfrx-tools to extract the SAQ message. The SNR was much stronger on the N-S loop than from the E field. Mixing E and H (including a small portion of the E-W loop) resulted in an SNR increase of > 6 dB. But in the end i used SpecLab to build the CW filter, a rough noise blanker for the very loud sferics (12 dB threshold) and finally a slow AGC which made it even more comfortable to listen to...
